Sticker-price tuition alone understates real college costs - this calculator totals the full Cost of Attendance figure financial aid offices actually use.
Cost of Attendance (COA) = Tuition/Fees + Room/Board + Books/Supplies + Other Expenses
Example
$15,000 tuition/fees, $10,000 room/board, $1,200 books/supplies, $2,000 other:
COA = $28,200.00
Why COA Is the Key Baseline Figure
Cost of Attendance is the standard baseline financial aid offices use to determine total need-based and merit-based aid eligibility, since federal aid rules cap total assistance at this figure - it always includes more than just tuition and fees.
Estimated, Not Guaranteed Figures
Room/board, books, and other expenses are commonly published as estimated averages by each school - actual individual spending can vary meaningfully, especially for off-campus housing costs or personal spending habits.
